Rated 4.9 out of 5 by 16 reviewers.
Rated 5.0 out of 5.0 by Needed new gasket for new sink Volunteered to do the plumbing work for a neighbor who was putting in a new countertop, sink and faucet. She has an Insinkerator disposal (Badger 5) but the mounting gasket needed to be replaced (would have worked but wouldn't look good in the new sink). Bought this product because one of the two gaskets was the correct one. Worked great, but then had one leftover that I didn't need. Why not sell them individually and charge half the price?

Rated 5.0 out of 5.0 by Quality replacement item was exactly as described and is an excellent replacement piece for the original gasket. February 9, 2015
Rated 5.0 out of 5.0 by Great It was easy to replace it. It was my first time so I was a bit hesitant to do it. Had to watch some DIY videos online and went to the store to see it for myself. Once I did it, it was really easy -- easier than replacing a bathroom faucet! Also recommend getting an "InSink Erator Evolution Series Antimicrobial Quiet Collar Sink Baffle" with it. It will look much better and quieter. March 22, 2015
Rated 5.0 out of 5.0 by np shipping charges, so price was good, quality and promptness excellent Problem with installation was that the disposal had to be completely removed from sink and all plumbing to replace the baffle.Then, of course, you have to deal with all the little leaks when put back together again.Also,aligning the disposal to the undersink holding ring was not easy. The disposal is very old, hopefully newer designs have done away with that. InSinkErator makes a great product. This one is still working great December 13, 2014
Rated 5.0 out of 5.0 by Worked as advertised The product worked as advertised. It was easy to install once you have the proper tools. Lacking was was which way to turn the locking ring to release the grinder. December 23, 2014
Rated 5.0 out of 5.0 by This gasket was very easy to install Our old gasket was worn out and half of it was missing. I found this gasket online, I ordered it for in-store pick up, and I found it was easy to install. I'm handy, but thought this diy project would be more complicated than it was. This only took about 10 minutes from start to finish. The gasket looks great and water and food particles stay in the garbage disposal instead of splashing up. I'm glad I made this purchase and I'd highly recommend it. December 31, 2013
Rated 5.0 out of 5.0 by Perfect Replacement for Original This part seals the place where the top of the disposer attaches to the bottom of the sink drain (hence the term "gasket") and also serves the function of blocking food particles from flying out of the disposer when it's running. I was concerned about Internet reviews of third-party after-market replacements that are stiff rubber and make it hard for food to go down the drain and for water to drain properly. This OEM part is a very nice soft rubber exactly like the original and allows food and water easily to go down the drain and not pop out. Installation requires disconnecting the J-trap drain pipe and unhooking the disposer under the sink and then reattaching, but both steps are quite easy for a reasonably handy do-it-yourselfer, especially with the disposer's easy-disconnect locking ring .

Rated 5.0 out of 5.0 by It works for its intended purpose Good price, easy install, works as intended. I like the fact that there's 2 in the pack. January 4, 2015
